I do not found a way to get an image description from an secure repository.
You configure your Mediawiki to get all your images from an external repository with $wgUseSharedUploads = true. And you want also fetch the image description from the repository with $wgFetchCommonsDescriptions = true, which is closed with "$wgGroupPermissions['*']['read'] = false;".
This works for repository, which are "open". When you restricted the access to the repository, so that only a login user can read the images pages, you get the image shown in the mediawiki, but no image description.
I follow the path and find out that in the HttpFunction.php works with curl, but there is no possibility to hand over a username and a password, or?
How to get the image description, like this?
